虚拟语气(SubjunctiveMood)
I.概念:
虚拟语气用来表示说话人的主观愿望或假想。
条件句:
1.真实条件句,假设的情况可能发生:
if从句 主句
一般现在时 shall/will+动词原形
Ifhecomes,hewillbringhisviolin.
TellEricifhedoesn’tattendthisexamnow,hewillregretit.
2.非真实条件句,即虚拟条件句。
虚拟条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。
II.虚拟条件句(非真实条件句)
1.一般的构成和用法:
if从句 主句
1)同现在事实相反的假设:
did(were) should(would/could/might)+do
2)同过去事实相反的假设:
haddone should(would/could/might)have+done
3)表示对将来的假想:
weretodo should(would/could/might)+do
shoulddo
(did/were)
Eg.IfIwereinyourposition,Iwouldacceptthejob.
Iftherewerenoeconomiccrisis,therecouldn’tbesomanyproblemsintheworldnow.
Ifyouhadaprivateplanewherewouldyougo?
IfIhadknownitwasyourbirthdaylastSaturday,Ishouldhavegotyouapresent.
Ifyourteacherhadnotbeenhereyesterdaywhatwouldyouhavedone?
.
Ifairplaneticketsshouldbecheaper,Ishouldgohomebyairthiswintervacation..
Ifyoushould(wereto)leavetoday,youwouldgettherebySunday.
2.省略if的虚拟条件句,即:
虚拟条件句的倒装。
Eg.Weretheyherenow,theycouldhelpus.
=Iftheywerehere…….
Had
money
year,I
would
bought
house.
=
If
money…….
Shoulditrain,thecropswouldbesaved.
=Wereittorain,….
=Ifitweretorain,…
3.混合条件句:
主句与从句的动作发生在不同的时间,谓语动词的虚拟语气形式因时间不同而不同:
Ifyouhadtoldmewhenyourplanewassupposedtoarrive,Icouldpickyouupattheairport.(从句与过去事实相反,主句与现在事实相反。
)
you,
taken
his
advice.(从句指现在,主句指过去)
Ifitshouldrainforseveraldaysonend,thesportsmeetwillbecalledoff(陈述语气).
“IfIhadn’tpracticedwhenIwasyounger,”themusiciansays,“Iwouldn’tbeabletoplay
4.含蓄虚拟条件句:
有时假设的情况并不以条件从句形式出现,而是用介词短语或其他方式表示,常见的有:
without,
but
for,otherwise,
or,under,suppose…
Eg.Without
snowstorm,
(=If
therewereno…),
couldhave
arrivedmuchearlier..
But
elect
